I'm not sure of the source of this, but it's a fairly good comparitive
survey of operating systems:
If operating systems ran your car, and you needed to go to the shops...
MS-DOS: You get in the car and try to remember where you put the keys.
Windows: You get in the car and drive to the shops very slowly, because
attached to the back of the car is a freight train.
Macintosh System 7: You get in the car to drive to the shops and the car
drives you to church.
Unix: You get in the car and type 'grep store'. After reaching speeds of
200 mph en route, you arrive at the barbershop.
Windows NT: You get in the car and write a letter that says "go to the
shops". Then you get out of the car and nail the letter to the dashboard.
Taligent/Pink: You walk to the store with Ricardo Montalban who tells you
how wonderful it will be when he can fly you to the store in his LearJet.
OS/2: After fuelling up with 6000 gallons of fuel, you get in the car and
drive to the shops with a motorcycle escort and a marching band in
procession. Halfway there, the car blows up, killing everyone.
S/36 SSP: You get in the car and drive to the shops. Halfway there you run
out of fuel. While walking the rest of the way, you are run over by kids
with mopeds.
AS/400: An attendant kicks you into the car and then drives you to the
shops where you get to watch everyone else buying filets mignon.
